Preheat the oven to 375˚ F. In a medium bowl, combine the cream cheese, mayonnaise, green chiles, jalapeños, and shredded cheeses. Mix thoroughly with a spoon or spatula until smooth and evenly combined. Spread the mixture into a baking dish (approximately 9 x 9-inches).

In a second bowl, combine the Panko and Parmesan and stir with a fork until combined. Sprinkle over the cream cheese mixture in the baking dish. Spray lightly with cooking spray. Bake for 25-30 minutes or until the mixture is hot and the topping is golden. Serve warm with baguette slices, vegetables, etc. as desired.
